INTERLEAVING APPARATUS.

Application filed June 13, 1927. Serial No. 198,548.

The present invention relates to apparatus toi-piling sheets, and inter-posing at intervals between a series of sheets, a sheet of a different character. `For example in the 6 manufacture oi tablets, sheets oli paper may be ruled and deposited in a lay-boy or other Apiling mechanism, and at intervals backing sheets ot card-board can be deposited in the lav-boy, thus creating a pile that may be lo aiiterivards formed into completed tablets. lt will be understood that it is not limited to the above specific example, but may be employed in various Ways well known to those skilled in the art. p

Figure 12 is a cross sectional viev1 ot the table ot the interleaving feeder and. its sup porting means. ln the embodiment illustrated, two trames 13 and 111-, are employed. In advance ot the trame 13 is located a feeding mechanism, designated generally by the reference numeral 15. This mechanism maybe ot any Well-known type, an example of which is that disclosed in my (3o-pending application,

l Serial No. 198,549, :tiled June 13, 1927.

`In the embodiment disclosed, the feeder shown as taking the paper from a roll 16 and passing it around rollers 16 and thence through a cutter consisting of coactingl roll* ers `1i'` and 18 rlhe roller 17 has a lrni'lc bladel9 cooperating with a ledger bar 20 carried by the roller 18.

In the rear end of the trame 141 is a layboy 21 that may be of `any Well-known or desired character. Preferably, however, its construction corresponds to that disclosed in my prior Patent,No. 1,560,015, dated No vember 3, 1925.

Mounted on the rear end of the traine 1B is ruling mechanism, preferably in the torni oit disc ruling devices, shown at 22. Lmver and upper coacting conveyor' tapes 2B and 2-l `carry the sheetsirom the feeder 1li to the ruling mechanism. Behind the ruling instrumentalities a conveyor, comprising a liront member and a rear member lille trout member consists of a lower endless cloth or tapes 27 and upper coacting cords or tapes 28. The rear member 2G comprises cooperating lower and upper tapes 29 and 3d rlhe member 26, as will be evidenti, de livers the sheets into the lay-boy 21.

interposed between the conveyor members 25 and 2G, and as shown more particularly in 'Figure 5, are convcrgently disposed guideways 531 and 32. These guidexvays are :Formed by a series oi' upper plates SBI-i can ried by across ro(L l, a lo wer series oli plates 35 carried by a er rod titi, and a series of intermediate triangular plates 37 mounted ou the cross rod 38. The upper downwardly inclined guideway 31 directs the sheets 'from the first conveyor member 25 to the second conveyor member 26, and said second conveyor` member deliversthe sheets into the lay-boy 2l.

`At the :front end of the rear trame 1li is locatcdan interleaving feeder, (ilesignated generally by the reference numeral 39.` This is a pile feeder, comprising a pile-:nuaporting .table 4 0, having` sleeves 41 slidably mounted on standards 42 (see Fig. 12), in the embodiment shown this table is hung on sprocket chains 113 that pass over sprocket Awheels L14- journaled on the upper ends of the standards. Suitable mechanism is employed for automatically elevating the table as the sheets are moved from the top of the ile. While this mechanism may be of y'any desirable character, preferably the following'lis provided. The sprocket wheels 44 are carried on shafts 45 which also carry worm gears 46. A cross'shaft 47 is provided, having worms 48 that mesh with the worm gears 46 (see Fig. 10). On this cross shaft 47 is fixed a ratchet wheel 49 (see Figs. 9 and 10). Loosely j ournaled on the shaft 47 alongside'the ratchetwheel 49 is a swinging pawl carrier 50, on the upper end of which is vpivotally mounted a pawl 51 that operates on the ratchet wheel 49. This pawl carrier has va depending portion provided with a pin 52 that'is engaged in the'slot 53 of a flink 54.V This link has mounted atv its other vend a crank pin 55 carried by a constantly Y rotating crankv disc 56.V The pawl carrier Y clear from Figure 3, when the pile of sheets on the table is sufficiently high, the arm 62 will be elevated, thereby swinging the detent armi 58 to a position beneath the Y,stop finger 57. The pawl carrier therefore will have noy active movement and the link 54 will slide freely on the pin 52. As the sheets are removed from the top of the pile the arm 62 will move downwardly until the varm 58 is moved out of the path i u of the stop finger 57 The pawl carrier will then swingrearwardly, so that the pawl 51 willv ride over one or more teeth -of the l ratchet Wheel 49, and as the link 54 moves `tion roller.

rearwardly,the pawl carrier will be swung in the opposite direction, thereby causing the, ratchet wheel 49 tov be turned. This effects the corresponding movement of the cross shaft-47, thereby rotating the shafts 45 and causing the elevation of the table until the detent 58 is again swung to a position beneath the stop finger 57 The means for feeding the sheets from the interleavingfeeder is preferably a suc- It is shown at 64 in Figures 5- and 6 and may be of any desired character, though preferably either like that shown in my Patent No. 1,494,303, May 13, 1925, or of the'character disclosed in my copending application-,f Serial No. 149,471. Connected to this lsuction'roller 64 is a suction conduit 65, which aswill be clear by reference to kFigures 1a and 1b leads to the intake side of a suitable fan 66. The Youtlet side of said vfan is connected byv a hose line 67 to blast nozzles, indicated al 68, which as is well known, serve to deliver blasts of' air against the upper edge of the pile of sheets to separate the same. In the conduit 65 at the first feeder is a controlling valve 69, shown particularly in Figures 1 and 7. This valve is preferably of the type disclosed in my former Patent, No. 1,408,688, dated March 7, 1922, and consists of a casing 70, through which the air passageway 71 passes. In this casing is a reciprocatory valve member 72 having a suitable port 73 that is movable into and out of alinement with the passageway 71 to permit or stop the flow of air therethrough. The valve member 72 in this structure is connected by a link 7 3a with one arm 74 of a bell crank element pivotally mounted, as shown at 75, and having its other arm 76 arranged in depending relation and limited in its movement in one direction by a sto 77. A ratchet wheel 78, journaled on the rst feeder 15, is provided with a sprocket wheel 79, around which passes a sprocket chain 80 that operates around a lower idler sprocket wheel 81. On this sprocket chain are mounted one or more lugs 82 that are adapted to engage the arm 76 and swing the same, thereby swinging the crank arm and moving the valve. The ratchet wheel 78 is engaged by a pawl 83 carried by an arm 84, and this arm has a link connection 85 with an eccentric. strap 86, and surrounding an eccentric 87, preferably mounted on one of the cutter rolls of the first machine.

It will be evident by reference to Figure 7 that upon the cutting and delivery of each sheet by the first feeder, the s rocket wheel 78 will have one increment o movement and the sprocket chain will be given a corresponding movement. Therefore at intervals a lug 82 will engage the arm 76, and consequently the valve will be elevated to open the conduit 65 to the suction side of the pump 66. When this occurs the suction roller of the interleaving feeder will be made active so that a sheet will be fed thereby.

It is believed that the operation of the apparatus can now be made clear. Sheets are successivel and continuously fed from the first fee er and successively passed through the ruling mechanism 22 and are delivered by the tangent conveyer members 26 and the interposed guideway 31 to the lay-boy 21. At predetermined intervals the suction roller of thc interleaving feeder will Vbe actuated as above described', whereu on the sheet will be fed therefrom and wil be directed by the lower guideway 32 to the second conveyor member 26 so as to be delivered thereby into the lay-boy. It is relatively immaterial whether the sheets from the first feeder and the second feeder meet and overlap at the entrance end of the conveyor 34 for said conveyor will carry all to the lay-boy 21. The consequence is that a certain number of ruled sheets will first be delivered, then a sheet, as for example a backing sheet of a tablet will be placed on the pile, after which another series of ruled sheets will be delivered and so on until a stack or pile has been produced. Obviously the number of sheets can be varied vand dif-- ferent combinations readily obtained.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it willbe understood that various changes in the size, shape, proportion and minor details oi' construction may be restorted to without departing from the spirit or sacrificing any oi the advantages of the invention.
